msm1267 writes: Researchers at Bromium Labs are expected to announce today they have developed an exploit that bypasses all of the mitigations in Microsoft’s Enhanced Mitigation Experience Toolkit (EMET). Principal security researcher Jared DeMott is scheduled to deliver a presentation this morning at the Security BSides conference explaining how the company’s researchers were able to bypass all of the memory protections offered within the free Windows toolkit.

The work is significant given that Microsoft has been quick to urge customers to install and run EMET as a temporary mitigation against zero-day exploits targeting memory vulnerabilities in Windows or Internet Explorer.

The exploit bypasses all of EMET’s mitigations, unlike previous bypasses that were able to beat only certain aspects of the tool. Researchers took a real-world IE exploit and tweaked it until they had a complete bypass of EMET's ROP, heap spray, SEHOP, ASLR and DEP mitigations.
